Understand
We consider power-law inflation with a Gauss-Bonnet correction inspired by string theory.
- We analyze the stability of cosmological perturbations and obtain the allowed parameter space.
- We find that for GB-dominated inflation ultra-violet instabilities of either scalar or tensor perturbations show up on small scales.
- The Gauss-Bonnet correction with a positive (or negative) coupling may lead to a reduction (or enhancement) of the tensor-to-scalar ratio in the potential-dominated case.
